Knew a kid that was really, really weird. When the school found out he has Aspergers, they let students know and explain it to us when he was out of the room. I thought it was weird but whatever.
6 months later, I was diagnosed with that stuff. In hindsight I didn't really feel like I had any of the signs until I hit about 6th grade, where I suddenly got panic attacks up the ass to the point where I couldn't even leave my house unless I was heavily medicated. I became a recluse over a 2-3 month period; By the time I eventually came back, lost nearly all my friends, except my current best friend, who stuck around even when I was gone.
I never really liked being labelled as a sperg because I thought it was too much of a crutch. I was doing fine when I wasn't labelled and I'm doing alright now. In fact, I'm doing so "well" that most doctors and people never notice I'm a sperg unless I specifically point it out to them, which I almost never do unless someone brings up the topic.
I've been using the terms sperg, autist, and autistic as an insult for nearly ten years just because I can get away with it.
That's the most I'll share without revealing too much about myself.
